When a clock divided by f(XIN) which is used as the timer count source?

Question:

(Clock) When a clock divided by f(XIN) is selected as the timer count source and the on-chip oscillator is selected in the clock frequency dividing ratio selection bit of the CPU mode register, which is used as the timer count source? [2005/03/01]

Answer:

f(XIN) is replaced by on-chip oscillator output. For example, if f(XIN)/2 is selected as a count source, it is replaced by Rosc/2. The same applies to timer 1, A, X, serial I/O, A/D converter and WDT. (#104960)
